Silver halide photographic light-sensitive material

Abstract

A silver halide photographic light-sensitive material is disclosed. The light-sensitive material comprises a support having thereon a photographic layer including a silver halide emulsion layer wherein the outermost surface of said photographic layer has a pH value of from 5.4 to 5.9 and said silver emulsion layer contains a compound represented by the following formula I; ##STR1## wherein R 1 is an alkyl group, a cycloalkyl group or an aryl group; R 2 is an alkyl group, a cycloalkyl group, an acyl group or an aryl group; R 3 is a substituent, n is 0 or 1; X 1 is a substituent capable of splitting off upon coupling reaction with the oxidation product of a color developing agent; and Y 1 is an organic group. The light-sensitive material is excellent in stability during storage and gives stable photographic characteristics even when pH value of developer is varied.

What is claimed is:

       2. The light-sensitive material of claim 1, wherein said compound represented by formula I is a compound represented by the following formula V; ##STR137## wherein R 1 , R 2 , R 3 , X 1  and n are the same as R 1 , R 2 , R 3 , X 1  and n defined in formula I, respectively; J is a --N(R 5 )CO-- group or a --CON(R 5 )-- grup in which R 5  is a hydrogen atom, an alkyl group, an aryl group or a heterocyclic group; p is 0 or 1; R 7  is an alkylene group, an arylene group, an alkylenearylene group, an arylenealkylene group or an --A--V 1  --B-- group in which A and B are each an alkylene group, an arylene group, an alkylenearylene group, an arylenealkylene group and V 1  is a di-valent bonding group; R 8  is an alkyl group, a cycloalkyl group, an aryl group or a heterocyclic group; and P is a bonding group including a carbonyl unit or a sulfonyl unit. 
     
     
       3. The light-sensitive material of claim 1, wherein silver halide grains contained in said silver halide emulsion layer are chemically sensitized only by sulfur sensitization. 
     
     
       4. The light-sensitive material of claim 1, wherein silver halide grains contained in said silver halide emulsion layer are chemically sensitized in the presence of elemental sulfur. 
     
     
       5. The light-sensitive material of claim 1, wherein at least one photographic layer contains a vinylsulfone-type hardener and a compound represented by the following formula H-I or H-II; ##STR138## wherein R 1  is a chlorine atom, a hydroxy group, an alkyl group, an alkoxy group, an alkylthio group, an --OM 1  group in which M 1  is a mono-valent metal atom, an --NR 5  R 6  group in which R 5  and R 6  are each a hydrogen atom, an alkyl group or an aryl group, or a --NHCOR 7  group in which R 7  is a hydrogen atom, an alkyl group or an aryl group; and R 2  is a group which is the same as that represented by R 1  except that R 2  cannot comprise a chlorine atom; ##STR139## wherein R 3  and R 4  are each a chlorine atom, a hydroxy group, an alkyl group, an alkoxy group or an --OM 1  group in which M 1  is a mono-valent metal atom; Q 1  and Q 2  are each --O--, --S-- or --NH--; L is an alkylene group or an arylene group; l and m are each 0 or 1. 
     
     
       6. The light-sensitive material of claim ! , wherein said silver halide emulsion layer comprises silver halide grains having a silver chloride content of at least 90 mol %.
